Honda unveils new 3.5-liter racing engine

Honda is following Ford's lead and debuting the second twin-turbocharged V6 to be used by Daytona Prototypes in the United Sports Car Championship. The wait won't be long to see it on track because the new engine will debut with the Starworks Motorsport team in a Riley Gen3 prototype chassis at the 12 Hours of Sebring from March 12-15.
The new HR35TT engine is based on Honda's J35 production V6 found in a variety of its models, including the current Accord. The racing version benefits from dry sump lubrication, but is still similar to the production version with an aluminum block, direct injection and single overhead camshafts. It is fueled by 100-octane E10 fuel, but like many racing engines, exact power figures have not been released.

Honda Performance Development Thursday announced a new, 3.5-liter racing application for the versatile, production-based Honda V6 engine found in a wide range of Honda/Acura passenger cars and light trucks and now raced in multiple categories worldwide.

The Honda HR35TT twin-turbocharged V6 is expected to make its TUDOR United SportsCar Championship debut at the 2014 Mobil1 12 Hours of Sebring, mounted in a Riley Gen3 prototype chassis campaigned by Starworks Motorsport.

Previously, Starworks partnered with HPD to win the LMP2 class at the 24 Hours of Le Mans and World Endurance Championship in 2012, using HPD's ARX-03b chassis and Honda HR28TT twin-turbocharged V6, which also is derived from Honda's J35 series of engines.

Starworks becomes the second team to utilize Honda power for the new TUDOR championship. Extreme Speed Motorsports campaigns a pair of prototype class HPD ARX-03b Hondas, after a successful initial season with the same package in the 2013 American Le Mans Series.

"This is an exciting program for HPD and our customer teams in the TUDOR United SportsCar Championship," said Steve Eriksen, HPD Vice President and COO. "Adding Starworks, a team that achieved great success with us in 2012, in a prototype machine alongside the proven HPD-Honda combination run by Extreme Speed Motorsports provides HPD with a strong, balanced attack in the inaugural TUDOR Championship."

"It's a fantastic feeling to be partnering with Honda once again," said Starworks team owner Peter Baron. "No doubt we had amazing success with HPD in 2012, but unfortunately it was only a one-year program. We have had numerous conversations over the past two years about building a Daytona Prototype motor and we're thrilled to see it come to fruition. We absolutely love working with HPD and have been in collaboration to find a new opportunity to partner with them again. We will have our work cut out with the steep learning curve to get us to Victory Lane, but HPD brings determination and success to every program it touches. Although HPD already competes in the Prototype class, we feel this is huge step for the TUDOR series and Starworks is thrilled to be part of it."

Starworks Motorsport has compiled an enviable record in Daytona Prototype competition, with five race victories, including back-to-back wins at Indianapolis in 2012 and 2013; and a second-place finish in the Daytona Prototype team championship in 2012, with two victories and six podium finishes. That same year, Starworks became the first American-based prototype team to win an FIA World Championship since 1968, and HPD won its first world title in WEC competition.

The HPD-developed twin-turbocharged Honda engines to be used in the TUDOR championship are both derived from the Honda J35 series of production V6 engines, and include relevant twin-turbocharger technology, along with the efficiency provided by direct fuel injection.

The HR35TT is yet another competition application of the ubiquitous J35 engine. The first, the HR28TT, was designed for LMP2 competition and won in its American Le Mans Series debut in 2011. The engine has gone on to record 24 individual race victories and three series titles in the American Le Mans Series, World Endurance Championship and European Le Mans Series Competition.

Other variants of the engine have been raced in Japan's Autobacs SuperGT Championship, the One Lap of America competitive rally and Pikes Peak International Hillclimb.

Karl Benz? As in Mercedes-Benz? The guy who built the Benz Patent Motorwagen and paved the way for the modern automobile as the inventor of the gas-powered automobile? That Karl did more than the Monte Carlo ever did for the advancement of automobiles. Foot, meet mouth.

Hate to break it to you Monte but there isn't a current Honda product I'd want. Or even want to be seen in. . Well, an Accord V6 coupe would be nice.... I'm sure you've seen the tail lights of one from your Monte.
And funny that someone too scared (insecure? embarrassed?) to use any part of their real name would try to find issue with someone else's name. Since there are no Monte Carlo highlights to be had, by all means, tell us YOUR accomplishments.... First to not fall asleep working night security at the mall? First to fit 50 pepperonis on a medium pizza? Maybe first to spread 1 jug of windshield wiper fluid between 3 gas pump islands?

Why not? The engine on which this is based is far more efficient and smooth than the majority of its DOHC competitors. Number of camshafts does not directly correlate to anything except the total cost of camshafts.

Who gives a **** how much power per liter it makes? If it's compact, lightweight, less complex, and makes just as much power, then it seems to me that HP/liter is an irrelevant statistics invented by ricers to make themselves feel better.
